Abstract

We study an economy with segmented financial markets and strategic arbitrageurs who link these markets. We show that the equilibrium of the arbitraged economy is asymptotically Walrasian in the sense that it converges to the equilibrium of an appropriately defined competitive economy with no arbitrageurs. This characterization serves to clarify the role that arbitrageurs play in integrating markets.
